Abstract (en)
[origin: WO2019228570A2] Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage devices, for data processing. One of the methods includes determining, by a storage system from an index log file, information of a data log file stored in a storage device. The data log file includes one or more of block data, transaction data, or state data generated by a blockchain network. The storage system determines whether the data log file needs a rewritten placement. In response to determining that the data log file needs a rewritten placement, the storage system determines a source storage location of the data log file, reads the data log file from the source storage location, rewrites the data log file to a destination storage location; and generates a destination index log file that indicates the destination storage location corresponding to the data log file.
